For example, emissions of NO concentrations did rise with the increase of road transport, until catalytic converters and increasingly stringent emissions standards led to a decoupling of emission trends from transport development.

In parallel, concentrations of ground-level ozone (O concentrations.

In much of the industrialised world, policy interventions to address the challenges of wide-spread air pollution as resulting from development and economic progress in the 2nd half of the 20th century have overall led to reductions in air pollution levels and related health effects since the 1970s.

While overall improvements towards reducing health effects from ambient air pollution are recorded, comprehensive and consistent assessments of the long-term impact of policy interventions are still scarce.

What is Air Pollution Air Pollution contamination of the atmosphere by gaseous, liquid, or solid wastes that can endanger the health of human beings, plants, and animals, or that can damage materials, reduce visibility, or produce undesirable odors.

Air Pollution Statistics Every year, more than sixty-six million tons of poisonous gas is emptied into the air, twelve million tons of hydrocarbons1, six million tons of nitrogen oxides, one hundred fifty thousand tons of aldehydes2, and five hundred thousand tons of sulfur compunds.

In addition, monitoring networks are typically sparse, which is a challenge when using monitoring sites to represent population exposure (Willocks 2018), but observational air quality data, whether ground-based or from remote sensing can only reveal the combined effect of changes in emissions, land use, and meteorological conditions on the formation, transport and environmental fate of pollutants.

Atmospheric chemistry transport models (ACTMs) explicitly consider all of these processes, and can be used to forecast as well as to reconstruct historic scenarios.

To address this evidence gap, we modelled the effect of four decades of emission reductions across Europe on UK annual mean concentrations of regulated air pollutants and their health impacts at ten-year time intervals of 1970, 1980, 1990, 2000, and 2010.

In order to focus on the impact of emission changes brought about by policy measures, all model runs were conducted using the same meteorological input data, varying only the emissions using available historic emission inventory data.
